Deoxys had to hide in the Pokémon world because of the force created by the meteor. The geomagnetic forces were too powerful for it to handle and caused it intense pain. Deoxys took Max to another dimension to try to communicate with him about what was causing it pain. In order to do that though, Deoxys also kidnapped Meowth to speak with Max.

To get Max back, Ash, Brock, May, and Solana fought Deoxys to get it back to its Normal Forme for Solana to capture it. After the meteor was destroyed, Solana used a Miltank's Heal Bell to heal Deoxys. After it was healed, it flew off and neither Deoxys nor the unnamed world have been seen since.
